Description

With the footwear improving sole

Technical field

The present invention relates to walking or sport shoess, its upper of a shoe is double-deck, and described upper of a shoe includes external jacket in this sense And internal jacket (enveloppe).This footwear can be used in as walked on level land or in mountain and running, skateboard, ball fortune In dynamic, distance skiing (le ski de fond) or revolution skiing, snow, surfing, snow boot (raquette à neige) etc. are led Domain.

Background technology

For the use considering, each footwear especially should have certain flexibility and good buffer capacity.Flexibility should Understand that tail meets the ability of some deformation of foot.It is related to so that foot is stretched well in the process of walking.As for buffering Effect be to reduce even to stop and by supporting or may strike against on ground or fatigue that various stimulation leads to or wound.

Footwear also should have various functions, these functions be sometimes mutually contradictory, such as ensure foot enough holdings fixing and/ Or fasten, provide gratifying comfortableness for foot simultaneously again.

It is thus known that the footwear shown in manufacture Fig. 1 and 2, a part for the accompanying drawing that described footwear composition will be shown below.According to These figures, the footwear 1 that all or part cross section represents include outsole 2 and upper of a shoe 3.Upper of a shoe 3 includes the first sheath 4 and second Sheath 5, the two is all used for directly or indirectly covering foot.First sheath 4 is combined with the first assembling sole 6, is fitted with forming first (chaussant) element 7.Similarly, the second sheath 5 and the second assembling sole structure combinations, are fitted element 9 with forming second, and this Two elements 9 that fit are assemblied in the first inside fitting element 7.Second fit element be often soft footwear.Therefore, assemble sole 6,8 A part for composition insole 10.First sheath 4 of footwear 1 especially extends at outside 11 and inner side 12, and the first assembling footwear At the major part at bottom 6.This structure is traditional, because the first sheath 4 is pasted onto on assembling sole 6 by glue-line 13.Assembling Sole 6 is harder sole, so that the assembling process of the also referred to as first assembling of tolerance.Paste by tractive sheath 4 so that handle Sheath 4 is flattened on and carries out so that a shoe tree can be inserted in fits in element 7 on assembling sole 6.This is called the tradition dress on shoe tree Join.This makes it possible to apply enough pressure during the heating of glue, obtain first to fit element 7.Fit as second Element 9 is for example formed by making the second sheath 5 be connected together with the second assembling sole 8 by suture 14.This is called gating assembling. Sole 8 is the soft sole that can suture, and is called gating sole.In addition the en-block construction of molding or any equivalent can be set Structure.

Certainly, first element 7 that fits is fixed and is fastened for the holding ensureing foot, and second element 9 that fits has other Function, such as brings certain comfortableness.As supplementing it was observed that, first element 7 that fits is connected in one by glue-line 15 and outsole 2 Rise.Finally, the footwear 1 of Fig. 1 and 2 have certain flexibility and certain buffer capacity.

Usually, the soft footwear with two elements that fit of prior art has the disadvantage that：Due to hard first dress Join, described soft footwear also hinder the stretching, extension of foot at least in part, especially to running, and support, impact and other biography stimulating Pass is strongly.In other words it is known that footwear lack flexibility, and buffer capacity is not enough, because combining with glue-line 13 Sheath 4 turnover part produce increase footwear hardness thickness surplus.

Further drawback is heat-insulating shortcoming.In fact, for difficult use condition, such as walking in snow, user May feel that foot is cold.This is because the joint in upper of a shoe and outsole forms heat bridge, and this heat bridge is by the tradition assembling on shoe tree During operation, the extruding of material is formed.In fact, in this operation, needing very strong adding is carried out on the material constituting sheath 4 Hot and very strong tractive.

Further drawback is the shortcoming making difficulty of tradition assembling.In fact, sheath is made on assembling sole by stickup In place is the careful process of a comparison.Need for this high-power and accurate machinery carry out stretching on sheath, in place and Paste.

The intrinsic further drawback of some known soft footwear is that second element that fits is steady in the first position fitted in element Qualitative poor.For example take out foot with sometimes resulting in the second element relative first element contretemps mobile.

Content of the invention

For this reason, it is an object of the invention to provide improved footwear.Particularly the present invention makes every effort to be easy to make foot with several conjunctions Stretch in the footwear of foot element, and improve its buffer capacity.

The present invention also makes every effort to ensure that the relatively another element that fits of element that fits keeps fixing.

The present invention also wants to bring good heat insulation, particularly in the joint of upper of a shoe and outsole.

The present invention also strives for simplification the manufacture of footwear, and reduces production cost.

For this reason, the present invention proposes to include the footwear of sole and upper of a shoe, this footwear extends up to front end from rear end in length, in width The upper extension between outside and inner side of degree, extends up to upper end from sole in height, and footwear include first and fit element and the Two fit element.

The footwear of the present invention are characterised by, first fit element include the first sheath and first gating (strobel) type footwear Bottom, makes the mode that the first sheath is connected together with the first gate type sole include suturing, and second element that fits includes the second shield Set and the second gate type sole, make the mode that the second sheath is connected together with the second gate type sole include suturing.

Using suture so that sheath and gate type sole connect together the structure that can keep sheath and gate type sole.This is special Be not mean sheath and gate type sole in the fabrication process not by or hardly by overall elongation, compression or change.Therefore, The thickness of such as sheath or gate type sole keeps constant or nearly constant along their whole expanded range.It was additionally observed that, seam Conjunction technology is carried out by using the more soft gate type sole of the gate type sole that uses than technology for applying.In fact, pasting In the case of technology, assembling sole structure becomes and applies and application pressing force on sole for tolerating sheath, and so that sheath is being glued It is held in place after patch.Footwear to the present invention, these restrictions all occur without, and this just makes upper bottom and/or sole flexibility Than prior art footwear bigger.The gate type sole that these can suture is formed by soft and/or padded coaming.Therefore, originally The more preferable flexibility of the footwear of invention can preferably absorb the energy relevant with impact, collision or various stimulation.

The more preferable stretching, extension of foot in consequent advantage, can be enumerated, and be integrated with more preferable cushioning effect.

It was additionally observed that second fits the good positional stability that element fits in element first.In fact, suture skill Art can use accurate model (patronage), and this finally gives the accurate geometry of element of fitting.Therefore be easy to into Row gapless and do not have the adjustment of stress in the first element for second element.One of thus obtained advantage is to make foot more preferable Be maintained in upper of a shoe.

The footwear of the present invention has more preferable heat insulation, the joint especially between upper of a shoe and outsole.This be due to Protect sheath and/or the constituent material of gate type sole.This protection is certainly using the result of suturing skill.Do not need to strain Or heating material.It is noted that the technology of the present invention simplifies the manufacture of footwear, make the manufacture of footwear more economical.

Specific embodiment

The first embodiment being described below for example relates to the footwear walked on a hard floor or in snowfield.But It is, present invention could apply to other fields as previously mentioned.

By Fig. 3 to Fig. 7, first embodiment is described below.

As Fig. 3 illustrates, walking shoes 21 are used for accepting the foot of user.In known manner, footwear 21 include outsole 22 He It is arranged in the upper of a shoe 23 on sole.Footwear extend between rear end or heel 24 and front end or toe cap 25 along longitudinal L in length, and And transversely W extends between outside 26 and inner side 27 on width.

As illustrated, upper of a shoe 23 includes the lower part 30 for surrounding foot and is used for surrounding ankle and surrounds if necessary The upper part 31 of the bottom of lower limb.But, from hereafter will be seen that it is also contemplated that only including the upper of a shoe of lower part.

According to the first embodiment of description, footwear 21 extend up to upper end 32 from outsole 22 in height, that is, extend straight Free end to upper part 31 or upper of a shoe 23.

Footwear 21 are configured for so that foot can stretch in the process of walking well, transmit sensory information and for propping up Support or accept impact.Here it is the reason why outsole 22 and upper of a shoe 23 are soft.

Footwear 21 also include the first tie down device 35, for fastening upper of a shoe 23 with reversible manner.Here this device 35 is not entered Row description, because it is known to those of skill in the art.However, it has been observed that all the time within the spirit of the invention, permissible Consider that footwear 21 are not equipped with tie down device.In other words, in this case, upper of a shoe 23 from outside 26 until inner side 27 is continuous 's.

Recognize in particular such as by Fig. 4 to Fig. 6, footwear 21 include first element 41 and second that fits and fit element 42. Will be better seen below, first element 41 that fits is that direct exposure may be with the outer member of bar contact.First tie-down Device 35 is further placed on this element 41.Therefore, second element 42 that fits is for being inserted in the inner member in the first element 41.

According to the present invention, first element 41 that fits includes the first sheath 43 and the first gate type sole 44, the first sheath 43 The method connecting together with the first gate type sole 44 includes suturing 45, and second element 42 that fits includes the second sheath 46 and Two gate type soles 47, the method that the second sheath 46 is connected together with the second gate type sole 47 includes suturing 48.

As for the vocabulary using, traditional strictly observe (respect) is with the first and second gate type soles 44,47 This two words, so named are because that sole is used for being sewn to sheath 43 and 46 respectively.For the ease of reading, the present invention is simple Ground is using the first gating sole 44 and the second gating sole 47.

Due between the first sheath 43 and the first gating sole 44 using suture 45, first fit element 41 have larger Flexibility.This means that the flexibility of this element 41 is more than the softness obtaining by the traditional mounting technology pasted on shoe tree Property.Certainly, second element 42 that fits is also very soft, because it is also by the technology different from the assembling pasted on shoe tree Obtain.Therefore, footwear 21 have larger flexibility, the junction especially between upper of a shoe 23 and outsole 22.Therefore just In stretching, extension during walking or running for the foot.

Above-mentioned advantage is obtained by the sheath 43 and 46 with known ordinary construction.Therefore, even if simplifying them Diagram, according to apply the first sheath 43 include one layer or which floor.For example, the first sheath 43 includes outer layer, interlayer (ame), interior Layer and lining.Identical spirit in, the second sheath 46 include one layer or which floor.For example, the second sheath 46 includes an insulation bubble Foam layer, or also include a waterproof sealing membrane, or the combination of the two.In the case that suture (couture) is formed on diaphragm seal, Described suture can be covered with a kind of material or a band, and described material or band are used for blocking the eyelet producing during suture.? Afterwards, upper of a shoe 23 includes at least two sheaths 43,46, and the machinery of this at least two sheath, physical property are different.

It is noted that footwear 21 include insole 55, this insole 55 includes the first gating bottom 44 and the second gating sole 47.Can Additionally include unshowned cleaning sole to arrange insole 55.Certainly, this cleaning sole fits unit because being arranged in second Contact with foot in part 42.

In view of all constituents (ensemble des constituant), footwear 21 are included by outsole 22 and interior footwear The complete sole 56 that bottom 55 is constituted.Due to first fit element 41 need to by suturing skill, select than on shoe tree paste biography Soft the first gating sole 44 much of assembling sole used in system technology.This flexibility makes it possible to realize suture.This is just It is the reason complete sole 56 of the why present invention is more soft than the complete sole of prior art.

For example, in a non limiting manner, the flexibility of the first gating sole 44 is substantially equal to the second gating sole 47 Flexibility.This means that the flexibility of the first gating sole 44 is equal to the 50% about of the flexibility of the second gating sole.Also may be used To say, the hardness of the first gating sole 44 is equal to the 50% about of the hardness of the second gating sole 47, even if these hardness are all relatively Little.By comparing, in the prior art, in the technology pasted on shoe tree, the hardness of the first assembling sole is equal to or more than the Two fit element the hardness of gate type sole 150%.

As understanding by Fig. 4 to 7, in order to construct the footwear 21 according to first embodiment, make the first sheath 43 and the The suture 45 that one gating sole 44 connects together extends in the whole joint of sheath 43 and the first gating sole 44.In other words Say, suture 45 encloses the first gating sole 44 around around.This gives first and fits the maximum flexibility of element 41.Alternatively, Local suture can be set, and do not using glue using the place of suture.In this case, some part ratios of element 41 Other parts are more soft.

According to same principle, make suture 48 that the second sheath 46 connected together with the second gating sole 47 in sheath 46 and Extend in the whole joint of gating sole 47.Suture 48 encloses the second gating sole 47 around around.Therefore, second fits unit The flexibility of part 42 is maximum.Also can in addition consider that local sutures.

In order to the footwear 21 being completely assembled are it is necessary to make upper of a shoe 23 connect together with outsole 22.More precisely, here First fit element 41 by glue-line 60 pass through paste connect together with outsole 22.

It is noted that in a non limiting manner, which floor outsole 22 includes：For example it is used for the wearing layer contacting with ground 61, and put the cushion 62 fitting between element 41 in wearing layer 61 and first.It is known that wearing layer 61 include rubber or Any anti abrasive material.As for cushion 62, it includes absorbing material, such as polyvinyl acetate ethylene fat (é thyle vinyle Ac é tate) (EVA) foam or any equivalent material.Certainly, outsole 22 can include monolayer, or on the contrary, including three layers or More layers.

According to first embodiment, outsole 22 has flank (levre) 63 in the joint fitting element 41 with first, To increase the contact area of the element 41 that fits with first.Here flank 63 is derived from cushion 62.Flank 63 is continuous, and along The periphery of outsole 22.Of course, it is possible in addition setting segmentation or discontinuous flank.But, continuous flank increase is used for making Outsole 22 fits the effective area that element 41 connects together with first.Therefore, glue-line 60 is along flank 63 and in outsole 22 Upper section 64 on extend.Therefore, this glue-line 60 is at the section below 65 of the first gating sole 44 and first sheath 43 Extend at bottom.

According to the first embodiment of the invention, second fit element 42 by the device that illustrated in the form of glue-line 70 with First element 41 that fits connects together.More precisely, the second gating sole 47 is passed through to paste and is connected in the first gating sole 44 Together.In addition other apparatus structures, the such as covering fabric with latch closure or hook can be set.As shown in fig. 7, the first gating footwear Bottom 44 has passage 73, and this passage is provided for being conducive to the in place of the composition glue of two glue-lines 60,70.These passages 73 are here It is temporary, because these passages are to be obtained by the partial cut gating sole 44.But can in addition arrange and pass through Cut the permanent channels obtaining completely.Also can arrange and glue is injected by hollow needle, or use thermoplastic.Glue 70 can make to fit Element for good and all keeps mutually fixing.

The method manufacturing footwear 21 can be summarized as follows.The method includes：Form first to fit element 41, described first fits Element is included by suturing the first sheath 43 assembling and the first gate type sole 44；Form second to fit element 42, described the Two elements that fit are included by suturing the second sheath 46 of assembling and the second gate type sole 47；Form outsole 22；By viscous Patch makes second element 42 that fits connect together with first element 41 that fits；And make outsole 22 be connected to first to fit element 41 On, so that the thickness t2 of the thickness t1 of the first sheath 43 and/or the second sheath 46 is the first shield in the joint with outsole 22 The thickness t2 of the thickness t1 of set 43 and/or the second sheath 46 is in the 50-100% of the value at a certain distance from this joint.

In fact, the thickness t1 of the first sheath 43 is substantially invariable particularly along outside 26 or inner side 27.Especially Engaging proximate between one sheath 43 and the first assembling sole 44 and to be originally in thickness t1 in this joint be substantially invariable.Change Sentence talk about, thickness t1 at the periphery flank 63 of outsole 22 and its near be substantially invariable.This is because first fits unit Application pressing force on outsole 22 for the part 41 is less.The constituent material of sheath 43 and the first sole 44 is protected, because its knot Structure keeps identical everywhere.Particularly, this structure is not irreversibly subject to crushing.In addition, in the present invention, sheath is not to be applied in Bear stretching on assembling sole.

Under digital angle, the thickness t1 of the first sheath 43 measured at suture 45 is at the top 75 of flank 63 The 90-100% of this same thickness t1 measuring.Equally little thickness change especially occurs from this snowfield on snow boots Boots are the footwear not having upper of a shoe tie down device, that is, its upper of a shoe from side 26,27 be continuous to opposite side.Sometimes observe, Suture the 50-100% that the thickness t1 at 45 is this same thickness t1 at the top 75 of flank 63.It is pasted onto assembling with by sheath This change less always is compared in the change observed in the conventional footwear of the assembling on sole, occurs in and is more suitable for harder On the footwear walked on the ground or run.In all cases, keep whole thickness t1 or at least keep the major part of thickness t1 can change Kind heat insulation.Joint between sheath 43 and outsole 22 remains this heat insulation.Do not have any to make one sorry heat bridge. The comfortableness of therefore footwear 21 is best, especially in snowfield.

Described above it is also applied for second and fits element 42.The thickness t2 of the second sheath 46 is particularly along outside 26 or inner side 27 is substantially invariable.Junction and its nearby between the second sheath 46 and the second gating sole 47, thickness t2 is perseverance substantially Fixed.At the periphery flank 63 of outsole 22 and its near thickness t2 be substantially invariable.Second fits element 42 first Application pressing force in element 41 is also less, or even very little.The constituent material of sheath 46 and the second sole 47 receives protection, because Its structure keeps identical everywhere.

The thickness t2 of the second sheath 46 measuring at suture 48 be measure at the top 75 of flank 63 this with The 90-100% of one thickness t2.Sometimes it was additionally observed that, at suture 48, thickness t2 is that this at the top 75 of flank 63 is same The 50-100% of thickness t2.

For some applications, the second sheath 46 is set and includes a waterproof sealing layer and/or a waterproof sealing membrane, and the second choosing Logical sole 47 also includes a waterproof sealing layer and/or a waterproof sealing membrane.Therefore, in this case, second fits element 42 It is the soft footwear of sealing or especially water-fast transmission.Even if being shown without, it is advantageously provided by being pasted onto the second sheath 46 simultaneously Upper and on the second sole 47 band covers suture 48.This band seals suture 48, the eyelet that blocking line passes through.It is of course possible to logical Cross alternate manner to be sealed, such as directly apply covering material, or the additional bottom (sursemelle) placing sealing.

Briefly represent second embodiment of the present invention by Fig. 8 below.Only display is different from first embodiment Part.

According to second embodiment, footwear 81 include outsole 82 and upper of a shoe 83.Footwear 81 be particular in that upper of a shoe 83 relatively Low, this upper of a shoe includes lower part 90 without entirely going up part in this sense.In other words, when user wears footwear 81, The upper end 92 of lower part 90 is located at below at ankle.Therefore footwear 81 are adapted well to walk or run.

Under any circumstance, using material and the technology implementation present invention of use known to those skilled in the art.

Certainly the invention is not restricted to previously described embodiment, but include entering following claim scope Interior all equivalent technologies.

Especially, can arrange and be further added by one or several elements that fit.Therefore footwear can include the 3rd and fit element.
